Characteristics and application of new ceramic nanofiltration membranes

In this study, the characteristic and filtration behaviour of a newly developed ceramic nanofiltration membrane was studied and compared to other commercial ceramic nanofiltration membranes currently available. It could be shown that it was possible to produce a ceramic membrane with separation properties in the nanofiltration range and with permeability rates clearly superior to that of polymer nanofiltration membranes. The ceramic membrane was used in tests involving the treatment of textile wastewater, alkaline solutions from bottle washing machines and pickling bath solutions.
